    摘要: A significant disadvantage of the use of polylactic acid (PLA), lack of flame retardance, has been overcome by the use of polyphosphonate-co-carbonate in combination with an impact modifier, a drip suppressant, and optionally, an epoxy functional styrene-acrylate oligomeric chain extender. The compound achieves a UL 94 rating of V-0 or V-1 and a Notched Izod value of more than about 5 ft-lbs/in. The compound also exceeds a threshold of 100 C in heat deflection temperature.
